--- Comment #12 from Roderick Colenbrander thunderbird2k@gmx.net 2008-02-28 03:38:25 --- The crash likely isn't in opengl at this stage. I think the msvcrt is the most severe one and I'm not sure why it occurs. Try to use a native msvcrt.dll perhaps it works better. (or the updater is doing evil things like e.g. updating the executable on the harddisk and in memory or whatever).
